Hose Bibs vs Water Main

I haven't seen anything mentioned about this yet. I'm planning on putting in a sprinkler system and am unable to connect directly to the water supply main in my home. The only place available are 2 hose bibs, one on either side of the house. I'm planning on using both as separate systems but not sure how to hook up the water supply. I'd like to use one timer to run a valve on each side of the house. THe 2 systems would take care of 1/2 of the property. I've seen small systems that use a short hose connections. I'd appreciate any help I can get.

I would make every attempt to connect to your main line due to flow. I am sure you are going to have reduced flow if you connect to your hose bib. Honestly it is normally very easy to connect to your main.

I wish I could. The main comes in from the street underground. Under the house slab and into a Laundry Room in the middle of the house. I looked at the service after the meter and there isn't room to sweat in copper. I haven't looked in the attic to see if there's pipes there. I do know most of the PVC in the house is 1/2" but not sure what's upstairs. I'll have to look there when I can.
Will advise further results.

I concur with drpete. The main may be 4ft in the ground but there must be a place before the line enters the house that you can dig down to and tap. A 1/2" line is most likely too restrictive and will short you on flow. Remember, a 1/2" line is only "half" the size of a 1" line but it carries 25% as much water NOT half. Hose bibb connection should be an absolute LAST resort. In addition, you would need two backflow devices. That additional cost would far outweigh even having it professionally dug.

I definatly want you to try and make an effort to tap to your main,,,,and if you absolutely no quetiones asked, i would find the pipe that goes out to your hose bibb, and chenge it to 3/4 or 1" and tap off of one, and bring the pipe around....i would have a pro tap into your main,,,,,,im sure an irrigation company would do it for you...we charge 400.00 to dig up and tap into the main because its 4-6 feet in the ground here!

Thanks to all. I really appreciate all your information. My wife and I think what we're going to do is to hire a contractor. We live in an over 50 community and several homes here have had a contractor put their systems in. THis seems the best way. I was looking into my attic this morning and can find some 1' pipes there but looking at other installatins here we feel the best way is contractor.
